Key matchup: Adams vs. Dumervil

In one of Week 4′s most intriguing matchups, 6-foot-7 Cowboys left tackle Flozell Adams is charged with slowing down 5-11 Broncos outside linebacker Elvis Dumervil, who is second in the league with six sacks.

That’s six sacks as in twice as many as Dallas has recorded through three games.

With his low center of gravity and long arms, Dumervil has drawn comparisons to the Steelers’ James Harrison. But Adams has yet to give up a sack this season, quite an achievement considering he’s faced the Buccaneer’s Gaines Adams, the Giants’ Osi Umenyiora and the Panthers’ Julius Peppers.

Dumervil, though, could be the quickest of the bunch and he’s got plenty of momentum after recording all of his sacks in the last two games. His play is a big reason why the Broncos’ lead the league in total defense (214.7 yards), scoring defense (5.3 points) and have given up just 16 points in their 3-0 start.

“He has the God-given ability to be able to get off the ball,” Broncos safety Brian Dawkins said. “He’s already low to the ground. He has long arms to get guys off of him and then he has a motor. He has an unbelievable motor that he feels he cannot be blocked if he is one-on-one with a guy.”

Said Broncos coach Josh McDaniels: “Elvis has always put up good statistical numbers as far as his production. I think he had 26 sacks in the first three years and has obviously done a nice job of getting to the quarterback this year. He works hard at it. He works extremely hard. He has a little bit of a unique skill set. He’s a shorter pass rusher who does have longer arms than most shorter players and he’s really bought into what we’re doing with him in our system and he’s really had some success here early in the season. He can get better. He knows that. He’s working hard every day to try to do that. We’re pleased with the production he’s given us so far.”
